• Optimize boot times, enhance robustness, and improve debug capabilities for Compute devices.
• Conduct product-specific use-case optimizations using real workloads, profiling, and end-to-end system analysis.
• Perform memory optimizations and performance tuning, including analysis of memory allocation, pressure, fragmentation, and latency.
• Own and deliver overall product power and performance KPIs, including measurement, tuning, and regression prevention.
• Mentor junior engineers, contribute to technical reviews, design documentation, and architectural discussions.
• Represent Qualcomm in upstream Linux and open-source communities through technical contributions and patch reviews.
• Enhance and support userspace resource-manager frameworks for effective power/performance trade-offs.
• Collaborate with cross-functional teams including Systems Architecture, Hardware Design, Power, Thermal, and OS (Linux/Android) teams.
• Work with the upstream community to resolve issues, regressions, and implement new optimizations.
• Triage and debug complex performance regressions using profiling tools such as ftrace and perf.

Required Qualifications

• 8+ years of experience in Linux software development, with a strong focus on Arm architecture.
